That Travel Agent was not acting in a very professional way. Any travel agent that is decent knows how to behave professionally and never states their own opinions on topics such as this. Each cruise line has something for everyone and some people prefer some to others but this in no way means that HAL is a bad cruise line.
What one person feels is bad, is not necessarily the same for another person and she should have realized this and kept her big mouth shut....
I have only sailed on Princess and I love this cruise line, but that does not mean that I won't sail on HAL. I certainly will, if the opportunity presents itself.
